WILLIABI E. JOHNSON. OF-ROCK ISLAND, ILLIXOIS, ASSIGNOR TO ROCK ISLAND'PLOW COM-' i PANY, OF ROCK ISLAND, ILLINOIS, A CORPORATION OF ILLIXOISf WHEEL-PLOW.

To all whom it may concern:

' Be it known that I, WILLIAM E. J OHXSOX, a citizen of the United States of'America, and resident of Rock Island, in the county of Rock Island and State of Illinois, have invepted a certain new and useful Im rovefnent in \Yheel-Plows, of which the fol owing is a specification.

,fMy invention rel'ates to wheel or sulky plows in general, but more particularly to wheel plows of that character in which pro.

I class in whieln the plow is supported by a wheels.

Generally stated, the object of my invention is the provision, in a wheeled or sulky plow,of any suitable character, of an improved arrangement of foot levers for raising bodv frame mounted on suitable vehicle and lowering the" plow; and a special object, is to provide an-improved construction and arrangement whereby the lifting footlever nia-ybe applied directly to the joint or articulation of the toggle connection employed for raising? and lowering the plow; and another object, is to provide an improved construction andarrangement whereby the depressing foot lever may be applied direc'tly'to the point where the said toggle connection is pivotall'ysecured to the plow beam; and a further object is the provision of an improved construction and arrangement whereby the lifting foot lever may be rigid with the lower arm or member of the said toggle connection which connectsthe body frame with the plow beam; and another object is to provide an im roved construction and arrangement where y the lifting of the plow may be accomplished through the medium of a toggle con- Iiection which-breaks joint downwardly and rearwardly when the plow rises; and it is also an objecttoprovide certain details and features of improvement tending to increase the general efliciency and serviceability of a plow of this particular character.

To the foregoing and other useful ends myinvention consists in the matters hereinafter'set forth and claimed.

having a foot lift arrangement embodyin the principles of my invention." Fig/2 is enlarged perspective of the said foot-lifta rangement, showing the adjacent portion the plow beam and the body frame, the two- 55 plows being raised from the ground. It will be seen that the plowshown in Fig. 1 is a gang plow, but it will, of course, be under-1 stood that one or more or any suitable num ber of plows may be employed without de'-. parting from the spirit of my invention, and that the improved foot-lift arrangement may be em loyed wherever it may be found ap- Fig. 3 is a view similar to Fig. 2, but showing the foot lift arrangement in the condition necessary for de ressing the low or plows. Fig. 4 is an en arged side e evation of the foot lift arrangement in the condition shown in Fig. 2. v Fig.6 is a plan ofthe parts as shown in Fig.- 4'. Fig. 6 is an en-' larged elevationof the foot lift arrangement in the condition shown in Fig. 3,. Fig. 7 is a verticaLsectionpn the line 77 of Fig.4." Fig. 8 is a perspective showing a ortion of the lower link or arm of the togg e connec- 30 tion. Fig. 9 'is a vertical section on the line 99 of Fig. 4;. Fig. 10 is a detail vertical section on line 1010 of Fig. 9. Fig. 11 is a detail perspective view of a'portion of the depressing foot lever. Fig. 12 is a detail perspective of the hub portion of the lower arm of the toggleconnection. Fig. 13 is a perspective of the removable and adjustable locking hook which is attached to the depressing lever. Fig. 14 is a perspective of 9 the upper end portion ofthe bracket or hous ing which is secured to the body frame, show-"--' ing the set screw which is employed as an ad justable stop for the upper link or member of the toggle connection, showing also the hookshaped lug engaged by the hook carried on the depressin lever, the twomutually en gaging hoo like member's constituting a: locking device for holding the plow or plows in an elevated position.

As my invention consists of a novel foot lift arran ement forraising and lowering ones: or more plows, in any suitable or-desired con+ struction of wheeled or'sulky plow, such, for example, as the gang plow shown in Fig. 1, 5 it willnot be necessary to fully describe. the cpnstruction and mode of operation of such a POI. -.{'.f

In a general way, therefore, the plow shown in Fig. 1 comprises a body frame 1A, 19

supported by wheels B, C and D. The wheel B consistsof a front furrow wheel of any suitable or desired character, while the Wheel Omay be a landside wheel of, any suit-' able known or approved character; the wheel D may be a caster wheel or-rear furrow wheel of any suitable form or characterf' .The rearplow E is'carried by the beam e, while the The two.

plow F iscarried by the beam el with each plow beams thus arran ed paral other and with one cut onger than the other,

are connected with the body frame by means of front and rear bails G and H, whereby the pllows may rise andfall in unison. A spring having one end connected with the rear bail and its other end connected. with a suitable portion of the body frame, assists the .driver in raising theplow, it being observed -fthat the middle or forward end portions of the two bails are journaled in' bearings secured to the plow beams, and that these portions of the bails swing up and down,'but never fall below their axes-that is to say, below the point where their lower. or rear ends are journaled in bearings secured to the body frame. Thus, with this construction, the two plows are. adapted to be readily raised and lowered relatively to the body frame, in a'manner side of the machine, so that it may be operated by the drivers left foot, part of the lift ing and lowering connection being applied to the beam e, and the remainin portions being.

applied to the left handsi e of the body frame A-that is to say, the landside of the machine. r

Referring to Figs. 2 and 3, itwill be seen that the lower link or arm K of the toggle connection has'one end pivotally connected with the bracket 7c secured to the beam e. As illustrated, this pivotal connection is effected through the medium of a'bolt 76 which passes through theup er end portion of the said bracket 70, and a so through the end of the link or arm K. It will also be seen that the other end of the arm K is provided with an outwardly extending l1ub-' portion k (see Fig. 9) provided with teeth k see Fig. 12, at its outer end. These teeth are adapted to 'be engaged by a similarly formed washer is which in turn is adapted to have a .toothed engagement with the end of the lifting lever L. A bolt is", which extends through said hub portion 75, the washer It and the end of the lever L, constitutes the means for rigidly connecting the said lifting lever with the arm K. The upper arm or member M of the said toggle connection has one end journaled or pivotally mounted, as shown, upon a cylindric hub portion k while its upper end is piyotally mounted upon the upper end portioii of the bracket or housing m, which latter is secured in any suitable manner to the body frame. There is a pivot pin or bolt m, arranged to extend through the said bracket or housing m and the upper end portion of the arm M, as shown more clearly in Fig. 9. And at this juncture it will also be seen that the rear bail H is preferably journaled in bearings carried by .the'said. brackets is and m. With this arrangement, said bails constitute the medium of shifting connection between the plow beams and the body frame, while the toggle connection composed of thearms K and M constitutes a lifting and lowering connection thatis to say, a iointed or togglelike connection which can be manipulated or operated for the purpose of raising and lowering the plows. Although the lifting lever L is, as stated, applied directly to the joint or articulation of the said toggle connection, and made rigid with the lower arm or member of said connection, it will be seen that the. depressing foot lever N is applied directly to the point where the toggle arm K has pivotal connection with the bracket 7:. In this way, the axis of the lifting foot lever L is coincident with the axis of the joint or articulation of the toggle connection, while theaxis of the depressing foot lever Nis 00 incident with the axis of the pivotal connection between the plow beam and the said toggle connection. Preferably, the depressing foot fever N is journaled or pivotally mounted upon the cylindric upper portion of the bracket k, as shown more clearly in Fig. 7.- It will also be seen that the depressing foot lever N also has a portion which is mounted on the bolt kfiivhereby the said depressing foot' lever has an extended hearing which prevents twisting or injurious straining of the different parts and connections. This is also true of the upper toggle arm M, as it not only has an extended bearing-or pivotalconnect-ion with the bracket carried y the body frame, but also affords an extended bearing or axis'for the lifting foot lever. In other words, all three of the pivots 'or axes about which the two toggle arms have movement, either relatively to each other or to the brackets to which they are connected, are of sufficient length to prevent the twisting or straining or lateral skewing which might result from the use of shorter axes or pivots.

lVith the toothed formation of the lever L, and of the washer 7c of the toggle arm K, and with the bolt 16 it is evident that the lifting lever can be adjusted and set at different po- 1 tion straddles the portion 7c, and the block 72- lever is then securely held in place upon the bracket by the rovision of a removable bearblock'n an a bolt n, as illustrated more clearly in-Figs. 2 and 7. Said U-shaped porfitsibelowsaid' cylindric portion, and between the -ends of said U-shaped ortion; The bolt n. passes through the en s of the U-shaped portion, through a;notch in the bottom of the lock The upper end portion of the bracket m is provided' with'a hook-shaped lugm and a set screw m which latter acts as anadjustablestop to limit the 11' Ward movement of the togg e arm'M. A ocking hook "it is adjustably secured to the depressing foot lever N, in the mannershown, and is ada ted, when the plows are raised relatively to t e body frame, to engage the hook-shaped lug or' rejection m In this way these two "hook s aped elements, one carried by the i body frame and the other by the depressing foot lever, constitute" mutual engaging de vicfesfor automatically locking the plows intheir raised positions, and for automatically unlocking the plows when it is desired to lower them. At this juncture itwill also be seen that the depressing foot, lever is provided with a short arm u while the lower .toggle arm K is provided with an opposing seat k: and a spring n is interposed between the arm .n? and'the seat or projection is. With this arrangement, the depressing foot lever is capable of some movement indegndently of and relatively to the toggle arm which movement is 'ust sufiicient, it

be seen, to disengage t e hook n from the lug m before the foot pressure applied to the said depressing foot lever is communicated positively to the toggle arm The lever N moves independently until-ittakes up' enough thereby raise the oint 0l4lIt1C1llatlOI1 of the of the lost motion to compress the springs n, and then the arm K begins to move causing it. to swing about its lower axis or point of pivotal-connection with the plow beam, and

toggle connection to the point shown in Fig.

3. The set screw rm limits the upward movement of the toggleconhection, and determines whether the joint or artlculatlon of such connection is to pass the center, so as to speak, or whether such joint or articulation.

is toremain slightly below the center line, .or directly on the line. It will be readily understood that the operator may adjust the uirements of any articular case, as maybe t ought best. If t e joint of the toggle connectionis permitted to rise above the center line, it is evident that the plows Wlll be locked plow connections w1 rigidly in their de ressed or lowered posi tions, and .thus he d rigidly in the ground. 1

On the other hand, however, the joint might be stopped before it reaches the center line, thus permitting the plows to rise of their own accord, should they .strike'obstructions of" difi'erent kinds. In this connection it will also be understood that'the direction of pull and the tension of the spring X can be regulated or determined in any suitable manner, for example, by a hand wheel nut Z.

. With a foot-lift arrangement of the foregoing character, I find that the plows are'easily manipulated, and are raised and lowered with very little exertion. As 'willbe -observed,- the foot-lift arrangement, and the connection between the body frame andthe' long'beam e, are located immediately in the rear of the rear bail H, which is the point of the heaviest load. When a downward pressure of the foot is applied to the lever L, the toggle joint is at once broken in a downward direction, and with theassistance of the lift ing spring the plows are then raised with the least effort possible. Stops of any suitable character can, of course, be located on the body frame to engage the balls or beams, or any other suitable movable parts,-and thus limit the downward movement of the plow beams, so that the plows will'b'ottom lightly just before the toglg assumed a straig t line; and with further pressure onthe depi'essing foot lever, the

against said stops; and if'at suchtime the e arms or members have a then be forced firmly toggle joint is just above the'dead center, so

to speak, the plows are then rigidlylocked in the ground.

will be seen that the point'of applying the lifting power is an important consideration, and in the present case islocated immediately above the load.
